摘　　要：2006～2007年在上海的自然条件、人工接种褐斑病菌(Rhizoctonia Solani Kühn)和涝害胁迫条件下开展了田间高羊茅草坪草(Festuca arundinacea Schreb)种质资源比较试验,对13个高羊茅草坪草种质资源的形态、色泽等坪用特性、抗褐斑病性和耐涝性方面作了较全面的评价。结果表明:引进品种平均评分第一的为"Duvana",得分8.7;其次为"Plantation",得分8.6和"Justice",得分8.4。我们自育的品种"沪青矮"及其组成成分的新品系具有株型较矮的遗传特性,综合性状评分居第3、4、5位(得分为8.5～8.4),也值得应用。在适当的管理条件下,例如:排水性良好的坪床,不少于每月1次的修剪、适当的肥水管理和及时的病虫害防治,上述推荐品种都能在长江中下游地区建植周年常绿的绿化草坪。A field study for evaluation of turf-type tall fescue （Festuca arundinacea Schreb） was conducted under the natural condition in Shanghai and artificial stresses by inoculating Rhizoctonia Solanl Ktihn and waterlogging between 2006 and 2007. Tuffgrass performances as lawn turf, including plant height, color, and stand density; and resistance to diseases especially to brown patch, waterlogging and summer stress, was evaluated for thirteen tall fescue entries. Results showed that among imported cultivars, ＂Duvana＂ ranked first with average ratings 8.7, followed by ＂Plantation＂ with ratings 8.6 and ＂Justice＂with ratings 8.4. Our domestic cultivars, ＂ Shanghai Evergreen Dwarf＂, and its component lines,＂SAC Dwarf＂ and ＂98-19＂ rated from 8.5 to 8.4, with genetic dwarf characteristics and are also recommended for application in the regions of middle and lower reaches of Yangtze River. The recommended cultivars could be established evergreen turf under good establishment and maintenance conditions, such as, cite preparation with good drainage system, regular mowing （no less than once a month）, suitable nutrition and water supply and timely pest control, in this area.
